Description
Die Erfindung betrifft eine Abgasanlage einer Verbrennungskraftmaschine mit einem, ein Abgas führenden Abgaskanal und einem in dem Abgaskanal integrierten, einen Katalysator umfassenden Abschnitt.The The invention relates to an exhaust system of an internal combustion engine with one, an exhaust leading Exhaust gas passage and integrated in the exhaust passage, a catalyst comprehensive section.
Es ist bekannt, ein von einer Verbrennungskraftmaschine kommendes Abgas mittels eines in einem Abgaskanal integrierten Katalysators zu reinigen. Dabei werden umweltschädliche Verbrennungsprodukte eines Luft-Kraftstoff-Gemisches wie Stickoxide NOx, Kohlenmonoxid CO oder unvollständig verbrannte Kohlenwasserstoffe HC an der Oberfläche einer katalytisch wirksamen Substanz zu unbedenklichen gasförmigen Verbindungen umgesetzt. In der Regel ist die katalytische Substanz auf der Oberfläche eines Trägermateri als (Monolith), das von dem Abgas durchströmt wird, fixiert.It is known to purify an exhaust gas coming from an internal combustion engine by means of a catalyst integrated in an exhaust gas duct. In this case, environmentally harmful combustion products of an air-fuel mixture such as nitrogen oxides NO x , carbon monoxide CO or incompletely burned hydrocarbons HC are reacted on the surface of a catalytically active substance to harmless gaseous compounds. In general, the catalytic substance is fixed on the surface of a Trägermateri as (monolith), which is traversed by the exhaust gas.
Bekannte Abgasanlagen weisen einen im wesentlichen linearen Aufbau auf, in welchem ein seitens der Verbrennungskraftmaschine angeordneter Abgaseinlaß den Abgasstrom dem Katalysator zuführt. Das so gereinigte Abgas verläßt den Katalysator über einen Abgasauslaß, der den Abgasstrom gegebenenfalls über Komponenten zur Schalldämmung einem mit der Umgebung in Verbindung stehenden Auslaß zugeführt, wo das Abgas die Abgasanlage verläßt.Known Exhaust systems have a substantially linear structure, in which is arranged on the part of the internal combustion engine exhaust inlet the exhaust stream feeds to the catalyst. The thus purified exhaust gas leaves the catalyst via a exhaust outlet, the exhaust gas flow optionally via components for sound insulation supplied to the environment related outlet where the exhaust gas is the exhaust system leaves.
Hinsichtlich des gegenwärtigen Trends in Richtung einer immer kleiner werdenden und kompakteren Bauweise für Motoren stellt die lineare Konstruktion einer Abgasanlage aufgrund ihres immensen Platzbedarfs einen erheblichen Nachteil dar. Das Problem des Raumbedarfs verschärft sich unter bestimmten baulichen Gegebenheiten um so mehr, wenn nämlich der Katalysator an Randbereichen des Motors angeordnet ist. In diesem Falle müssen Strömungselemente, die sehr viel Bauraum beanspruchen, den den Katalysator verlassenden Abgasstrom umlenken und zurückführen.Regarding of the present Trends towards an ever smaller and more compact Construction for Engines restores the linear design of an exhaust system Their immense space requirement represents a considerable disadvantage. The problem of space requirements the more so under certain constructional conditions, namely the Catalyst is arranged on edge regions of the engine. In this Trap must Flow elements, take up a lot of space, leaving the catalyst Redirect exhaust gas flow and return it.
